What Is a Leveling Screw?
A leveling screw, also known as a leveling bolt or adjuster foot, is a height-adjustment component used in machining operations. These screws are typically equipped with locknuts or spherical washers to maintain horizontal alignment and prevent loosening after installation.
Applications of Leveling Screws
Leveling screws are used to adjust the height and ensure the horizontal level of workpieces, machinery, and equipment. Commonly, they include a level adjustment screw for fine-tuning during installation. These screws often feature a hexagonal head or body for easy adjustment using a wrench and are widely employed in various machinery and fixtures.
Selecting the Right Leveling Screw
In selecting a leveling screw, it’s important to consider factors such as size, shape, load capacity, corrosion resistance, and the design of the adjuster foot, including angle adjustment capabilities. The size of the screw correlates with its load-bearing capacity, and the material choice, like stainless steel, affects both corrosion resistance and load capacity.
For specific applications like food machinery or environments with corrosive chemicals, materials compatible with the equipment or those with superior corrosion resistance are preferred. For installations on nearly horizontal pedestals, simple leveling screws suffice, while adjuster feet with angle adjustment functions are needed for sloping surfaces.
